Can jailbreaking solve this issue?

I have an iPhone 4s. The home button works only if you press it very hard. The mute and the power button screwed up. Can I transfer the functions of home button and power to the working +,- volume buttons as I can use volume from the control centre. Is this feasible?
PS: Instead I could change the power button strip, but those are hell expensive.

Your phone is broken… Fiddling with jailbreaking / buttons… Will not solve the issue… The phone is broken…
