This would have a severe impact on address computation for indexed loads.

There are likely other problems with non-power of 2 sized words, but just the difficulty with indexed loads is sufficient to rule out 40/80 bit word sizes. Bit aligning and masking an index is trivial compared to the integer multiplication required to be part of the indexed load instruction with those word sizes.
