I did look into this, and concluded "no".

The Py3 move would be much less compatibility-breaking, and would make
this task even more painful with no gain. Added my notes here:

Good point - this is something that we'll need to investigate. I'll
look into it on next opportunity.

Sugar Labs should not be held back by OLPC's schedule. The longer you
leave this transition, the more painful it gets.

Sugar is broken now, and we should do our bit to fix this, even though
it would not directly contribute to OLPC's next release it would
definitely have a very positive effect for OLPC's future releases.

Note that this change is not very disruptive, it just needs planning.
No activities would need to be ported immediately, and Sugar
components can be ported one by one. The porting process is expected
to be easy.

Disruption could perhaps be further minimized by requiring that
sugar-toolkit is ported to GTK3 and running stable before any other
work commences. But do remember that sugar-toolkit is proposed to
include the GTK2 version as well.
