Tbf, WVA, Van Baarle and Benoot have shown better climbing performances at GTs than guys considered pure climbers. Laporte is also very good for your 7th best climber and it's only really Van Hooydonck who's not an asset there.That's 5 classics guys and 3 climbers. I think 4+4 would be a safer balance. With Van Aert, Van Baarle, Laporte and Benoot they would still have crazy fire power for flat even without Van Hooydonck.
But we've all seen Van Aert, Van Baarle and Benoot climb like if they were pure climbers on occasion so it's very likely they will be OK.
