A SegWit commitment on the left hand side causes any permutation on the right hand side to force a recalculation of the left hand side.
This is still a non-issue as a solid GPU farm can crunch the SegWit version trivially and there are ASICBOOST compatible optimizations for SegWit that have not been publicly discussed.
One should look at the R&D on ZCash's equihash to see some of the work that has gone into collision finding.
