Thanks for all the comments. I swapped the 140mm Fox Float 32s for a set of 150mm Pikes (both 26″). Only done half a dozen rides and still tinkering with pressures, but so far it seems to be all positives.
The change in A-C was 17mm, which slackened head and seat angles by about a degree and raised the BB by 5mm. Nudging the saddle forward a bit took care of the seat angle and kept the pedaling dynamics the same. The slacker HA and longer travel, plus a bit of extra stiffness up front helps a bit on the way down and I’ve not noticed any extra problems on the way up yet. I thought I might notice some negative effect of the higher BB on the corners, but it seems to be more than offset by the extra mid-stroke support. It’s certainly easier to put some weight on the front.
It may be partly to do with the extra length, but I prefer it at 30% sag than 25%. Still good support, but lovely small bump sensitivity.
Anyway, just wanted to report back in case anybody else was considering the same change.
