using a stage1 as a compiler for a later ghc?

I'm on a system with main ghc = 6.4.2.
I've built a ghc 6.6 stage1.
Is there any problem using that ghc-inplace as a compiler for GHC HEAD?
(which is done e.g. by ./configure
-
--with-ghc=/home/isaac/hardly-mine-at-all/build/ghc-6.6/compiler/stage1/ghc-inplace
?)

(which I want to do because, theoretically 6.6 should be faster here,
since it supports -fasm unlike the ubuntu-edgy-powerpc-ghc-6.4.2, and
also considering how my gcc likes to crash randomly a few times during
anything as extensive as compiling ghc...)
