P Line wheelset is really really light.. not much room for weight saving there.
With new hubs and rims, the new wheelset on P (T?) is quite lean already.
Front，396g
Rear 578g，total 974g
3rd party light weight aluminum front 394g
rear with 4 speed compatible hub 551g so only 29 g saved
Still need more to get to target
PS. Even with top of the spec carbon rim spokes ceramic bearing Hubsmith BumBee P. CC349 (CE), the saving on weight is still only 80g (rated 120kg certified, light but not achieved by sacrificing safety.)
