In theory you could, but you'd have to map the tp1 brainmask to tp2.
Note that it might not matter that much because the cross surfaces are
not used during the base creation. I would see how things look in the
base, then edit the brainmask in the base if needed. The base brainmask
will then be propagated to the long time points, so maybe you only have
to edit it once, if at all.

External Email - Use Caution
Hello all,
I'm wondering if I can use brainmask or pial surface of timepoint1 as
a reference for the skullstrip of timepoint2. TP2 is being problematic
during skullstrip. I've tried -wsthresh and -gcut. Any option to use
brainmask1 as a reference point for brainmask2?
