IBM 5155 Portable PC CRT Sacrilege

So, I decided to buy an IBM 5155 Portable PC on the eBay, in part due to it being a lot cheaper than other 51xx machines I've seen listed recently since I started paying attention. Maybe it'll satisfy my desire for an early IBM PC, and I won't need to spend money on another? Yeah, dream on. :) I'll try putting an XT CF Lite into it; I ordered one in kit form, since soldering on the surface-mount CF socket doesn't intimidate me. I do have one misgiving about getting this machine, though: I don't like orange CRTs. I mean, I REALLY don't like them. So, at the risk of being virtually tarred and feathered, I shall don my asbestos long johns and ask a sacrilegious question: Is there any prior art regarding swapping out the CRT in a 5155 for one with a less offensive phosphor, such as green, white, etc.? I'm diving into my flame-proof bunker now... ;)
