There could be weight and righting moment issues.

Maybe it will be OK, but I guess I would at least want to do the math
before I poured the foam...

There could be possible corrosion problems.

Hollow masts are pretty resistant to oxidation. If you fill it with foam
it could easily develop pockets of poor drainage, and therefore corrode.
