Would this be do-able?
Could I replace my Epiphone G-310's neck with an LTD EC neck?
Thanks.

no. epi's have a 24.75" scale, ESPs probably use a 25.5" scale. the only replacement necks for these that ive found are DragonMountain on Ebay. they appear to be good quality necks but i havent gotten one...yet.
Douglas Spad with EMG 81x's
Epiphone LP jr. with EMG 89 split coil, alot of upgrades
Rig:
Power conditioner, Hush, ART Quadra/FX Reverb (all 3 in a rack), Peavey XXX, 2 Mesa 4x12 cabs.

Technically it's possible (nearly anything is possible with a painted guitar/one without a fancy top), but it's not at all sensible.

Buying an EC will likely be cheaper.
