Venom fighting stick with parts from a umvc3 hori? help please

Hi there,
Longtime lurker. Well i want to up my skills and customise the best stick!


So ive got an official hori Umvc3 fighting stick for ps3. Had it about 5 years. Does this have sanwa parts in it?

However, ive just bought the official ps4/ps3 venom stick as i can use it on both consoles. But the venom stick itself is too stiff and the buttons are not great.

However, the buttons and stick on the umvc3 fighting stick is great. Can i open up this one and put the parts in the new venom? (Saves me having to buy new parts)

And i believe both fighting sticks have a square gate. Could i simply buy an octagnol gate for the new venom (with umvc3 parts in).

And is there anything else i need to know, or any extra wires etc? And yet again is it sanwa?

Thanks in advance.
