I am joining a band.  We play metal/ hardcore.  The other guitarist uses a Mesa Triple rectifier.  I am thinking of getting some type of FRFR speaker setup, so that I can use the Kemper's speaker emulation.  Does anyone have experience with this setup?  The  Kemper is way more versatile for me since I do all the recording for the band
Of course they will work together... What do you think wouldn't work here?

I was thinking more so because I wouldn't be using a guitar cab.  Im not sure how a frfr speaker will sound next to a guitar cab since it won't be moving near as much air
Depends on the guitarists and their ability at tone shaping.  A good DMFX that has been carefully dialed-in sounds excellent through FRFR cabs in a band setting.  A Mesa is the same.  A good player will make either sound great and the tools used will be irrelevant.  How much air the speakers move is simply a function of SPL.  A frfr system that will produce clean output to 134db will melt a T Rec.  Here you go:

The opposite is also true.  A weak player can make either the Mesa or Kemper sound just gawdawful  and they will have great difficulty blending into the band or working with other guitarists.

Hope this provides some context and useful info.

It'll work fine, but there will  be a difference between them of course. The difference in db loudness hasn't got much to do with how many speakers you are using, but has more to do with speaker choice as well as the amps output power. You can consult speaker specs to get a bit of an idea, but I don't think you'll have any problems.

The difference in projection is difficult to accurately quantify, but becomes negligable if you are micing up the amps [or running the kempler direct to a pa or whatever], which you probably will be able to do for any reasonably sized gigs.

One of the main things I notice when using more speakers is more control over feedback over a wider range of physical space. If I'm using a 1x12 I have to be in certain place to get controllable feedback, but the more speakers the wider this sweet spot seems to become - of course this is even better if using multiple cabs over a wider physical space [ie a wall of cabs]

Been down this road before. You need about 400 watts of good clean solid state power to approximate 100 watts of tube power. a good 2x12 FRFR will get you in the ball bark as far as pushing air. Matrix amplification offer the best solution IMHO but that kind of quality goes in your pocket pretty deep. Worth every penny . You spent good $$ on your Kemper but it will only sound as good as your weakest link. Don't compromise on your FRFR system.

I have a pair of their 1x12's i run in stereo and would trade them for nothing.

I'm not sure where THIS comes from.
Output from the average 100W stack pushing a 4x12 of relatively efficient speakers will max out at around 120 dB, give or take. And it will weigh what, 125 lbs or more (head plus cab)?
An active FRFR (PA-type) speaker like the Carvin PM15A, which has a 15" LF driver and a 1.5" HF driver 400W RMS amp built in, will run about 122 dB (128 dB peak), will cost $249, will weigh under 40 lbs and can be put up on a speaker stand, used as a floor monitor, or put on a tilt-back amp stand.

I'm using a Carvin HD1500 with fEARful 15/6/1 speaker cabs (single 15 LF, 6.5" mids, 1" HF driver) that handle up to 900W at 8 ohms (and that's what the HD 1500 puts out bridged/mono). The HD 1500 (9 lbs) will also work with a pair of speakers, putting out 1500W at 4 ohms. The current Carvin HD3000 is $369 at the same weight.

Note that the Matrix power amp is not listed as stable at 2 ohms (the Carvins are) and you're not going to see a suggested rating for it for two 8 ohm speaker cabinets under bridged, mono.
