If you attack the bat bottom up you may need less wood off as it should help pickup. Better to lose 1-1.5oz off the toe than 3oz across all the hitting area. Toe could be trimmed down to 25mm without affecting durability, particularly if you go for a round toe and lose the toe guard (it will drop off in a few weeks anyway). Also angling the toe to avoid feathering will make the bat more durable and lose a little more willow. Losing the stickers might save 0.5oz, scuff a little more. Not helping pickup but another 0.2-0.3oz would be to slope the shoulders a touch, not quite shoulderless but between where they are now and shoulderless. Outside that, just take a mm or so off the edges and job done, each mm is an oz roughly.
