Mixing unmounted and mounted filters in wheel

Hello everyone,

I've got a set of Baader LRGB filters in 31mm unmounted format. I also have a Baader H-alpha 31mm unmounted. I haven't been able to find the Baader O-III or S-II in the unmounted format, only mounted. I don't think they produce 31mm unmounted versions

In light of this, I've bought an Optolong O-III 31mm unmounted, but am still undecided whether to go for a Baader SII 1.25" or look for a 31mm unmounted version.

Would there be any issues with using a mix of mounted and unmounted filters in my wheel? I have a ZWO 8-position EFW, which takes both formats.

Cheers
Stephen
