Can you use older Orbi satellites as satellites for the new RBK852

I have an RBK50 and am wondering if my RBS50 and extra RBW30 will work as extra satellites for a new RBK852 (Large home and i would love to use the 2 extra satellites out near the room over the garage and the guest bedroom/bathroom areas).

I know i wont be able to re-use the main router  as a satellite (can I??)  but it seems like both of the satellites, which are just basically range extenders would work????

I know they they officially released "universal" patches for both the voice model and outdoor ranger extenders (neither of which do i have) for this purpose but havent found anything about my satellites.

Not spending the $600 if i cant reuse some of the equipment to boost weak areas at the extreme ends of the home). 

If i can reuse some of it...i might be tempted.
