I think that it is practically impossible to do so from the point of

Currently Andrew Morton is carrying "linux-next.git only" patches
(a.k.a. CONFIG_DEBUG_AID_FOR_SYZBOT patches) via mmotm tree.
It would be nice if linux-next.git can directly import temp patches
using "quilt push -a" on patches from a subversion repository. Then,
we can casually add/remove/update temp patches like this.
