Having a GBM frontend is one thing I've been pondering as well.

Regardless of exact solution wrt the new allocator, having a clear
frontend/backend separation for GBM will be beneficial.
I'll be giving it a stab these days.

Disclaimer: Mostly thinking out loud, so please take the following
with grain of salt.

On the details wrt the new allocator project, I think that having a
new lean library would be a good idea.
One could borrow ideas from GBM, but by default no connection between
the two should be required.

That might lead to having a the initial hurdle of porting a bit
harder, but it will allow for more efficient driver implementation.
