Question Need advice: :Looking for D5 compatible Reservoir

TLDR: Need recommendations for a D5 pump compatible reservoir-NON-aluminum

I recently purchased a Bykski D5 Reservoir combo which is absolutely beautiful. Only one problem. It's caps are aluminum and my radiator and cold plate are copper. So I hit myself in the head when I realized this. (Good old galvanic corrosion makes this a no-no)

I should be able to swap out the D5 pump to a new reservoir. I just need one which has an appropriate pump head (side port G1/4" service connections) and not made of aluminum.
 
When you say the caps, are you meaning the G1/4" plugs?

Just buy new plugs, you don't need a new reservoir.

The tube itself if acryllic. The end caps are aluminum. Looks pretty but it won't work for me.

Unfortunately I didn't read the fine print on Ali Express about the materials used. So I want to scavenge the D5 pump (The most expensive part) and attach it to another reservoir.
