It is doable.
I reinvented myself about 7 years ago. Been out of it for ten / fifteen years or so (other than playing a bit for fun), and there have been lots of changes. Thanks in part to BM I've played with rather a lot of people and have written a bunch of new songs.
Also lots of stuff going on. The creativity of original bands has actually blossomed while the once despised cover band players have matured into a level of playing where damn good is the new normal. (there are several on this forum and they have it wired tight)
the other primary difference I noiticed was the technology - I quickly learned I'd have to count on myself - a tragedy!
So why not eh? Singers are ALWAYS in demand.
Good luck
