I currently have a 7’9” XH 1/2-4oz Fast Fenwick elite tech rod that I use for swimbaits and was wondering if it would double as a flipping rod or is it a bit too heavy?

I don't think the XH power is right, and with a rod that is both XH and quite long, it's probably going to be very tiring.  And even pitching does load the rod some, so this rod may be like a long broomstick.  

 

 

Costs nothing to try it though.  I could be mistaken.

With an old school Flipping technique or as a Punch Rod; I think it could work.

I think that's a bit overkill for flipping.  Like @MickD says, unless you're the hulk, that sucker is gonna tire you out fast.

Absolutely.  With flipping, all you are essentially doing is dipping the bait into a spot, and if a fish bites it, set the hook upward as you hoist them out.  

It isn't what I would use but if you are actually flipping or punching and not pitching, I'm sure it would work fine.
