I think I would swap ends and make the ends 220 …not hard to buy the right plugs.
If you are adding a load some thought should be given to load calculation. Small cabinets may not mean much but when you start adding lighting, fans, humidity control and temp control and breaking out subs you need to think about the main, the wire size and the existing load. It is not safe to add it without consideration and that is why electricians get paid to do that type of work. That and bringing the install to safety standards and local code.
