Designing a 2 way and may need to position midbass above tweeter. Tweeter will be in time aligned waveguide. Q I see most if not all designs with tweeter below have no baffle tilt. Will a baffle tilt of 4 degrees be ok? Height with stands will be 90cm, tweeter height around 70cm.
It's not really necessary; though mine are tilted slightly due to how close I am to them (small room).
The important thing is to get the offset right when designing your crossover. Get a tape measure and measure from the listening position. That will give you the correct offset for each driver.

In the past, tweeter below the midwoofer was done on a lot of speakers that used BW1 (norm polarity) and BW3 (rev polarity) to compensate for the downward polar tilt (approx -15°). Reversing the drivers can give an approx +15° tilt if offsets have been taken into account. This gives a ZDP (zero delay plane) close to 0°.
Hardly ever see it these days.
