I play in several bands, from tributes, to covers, to originals. There is always room for both, but perhaps less room for the original stuff, sadly.....
Though in fairness, I've played quite a few venues where they either like, want or tolerate original material - and those venues and crowds ARE out there. Trick is, finding them, together with appealing to the masses who want covers..... and winning them over.
A few covers, to get people singing & humming along, and tapping their feet or dancing, is no bad thing and handy to have in your repertoire.
Perhaps what you're really tired of, is the same covers or the same genres of covers? Seek out interesting / different covers and try a few

We've considered replacing the set, but TBH we've done the covers thing for 10 years (our first gig was the 7th Feb 2008, I still have the set list) and want to do something completely different. And Tammy's songs are too good to keep hidden. We will pop 2 or 3 covers in there too, I expect.  

Happened with my band - not 10 years, but a couple of years doing the Blues pub circuit, couple of new young members, written a whole load of songs and now going out in November on a 9 date national tour.  Good luck!
