Pretty sure that should be fine mate off top of my head. I don't think you really NEED the 90 degree bend tbh, I thought I'd need it from the oil filter breather to bend up towards the T piece coming off the cam cover breather, but the pipe is flexible enough to not need the bend. Luckily for me my hockey puck shattered when I had it out, so I ended up using the 90degree bend to drop back into the TIP... still haven't got a replacement sorted - really not sure how needed it is... All the searching I've done has come back saying that vacuum in the crank/cam cases is a good thing, so apart from possibly sucking oil vapour through the catch can back into the TIP (doubtful that vac is high enough in TIP with a cone filter on to do so tbh), I can't see there being an issue having a free flowing vent....
