Russian gunpods

I assume most of us are aware of the 23mm gunpods in the Russian arsenal, but I was wondering specifically about

– SPPU-22: this twin-barrel 23mm cannon pod with is intended for use on the Su-17M and MiG-27 series, and has 260 rounds- it’s a flexible model with GSh-23 cannons capable of delecting downwards. Can any aircraft use it, or just these aircraft? I was thinking about application on the Su-25

– SPPU-6: definitely my favorite gunpod- same as the SPPU-22 in operation, except carries the GSh-6-23 and an ammunition load of 500 rounds. It’s used on the Su-24 series. Again, same question- could it be used on the Su-25 or Su-32, for example?
