Good idea or not?

Im looking for versitality but it needs to do modern metal as well as possible.

If you can't get a good metal tone out of the amp as it is now, changing the preamp tubes is not going to change that.

Modern metal isn't really going to happen all too well in that amp, and has Al said replacing tubes isn't going to turn it into a differently voiced amp. They'll probably give your more gain and are awesome tubes, but won't give you modern metal instantly or anything.

right Metallica is a given. Personally I like to pretend the bus exploded and killed them all in '86.

Yes. those are good tubes for that amp.
Then slam the front end with an OD pedal for modern metal tones.
