Should i just go for thrills per mile?

[Nova Wake]

Ive been pondering a lift combo for quite some time now and pretty much have an idea of what i want, but gas prices are increasing a little and i am only mildly concerned about them, i was wondering if the drop in mpg would be worth it in sakes of fun and thrills. I was planning on a 4 in lift and 31's but found out it be close to the same price and mpgs just to go to 33's, i was planning on a clayton's 6.5 lift and 4.56's for my cry axle. I suppose i'd need a sye and a driveshaft, what is the complete run down of what i need to complete a total overhaul. I know i'll have a decrease in MPG but am i being overly optomistic by thinking i'll get around 15-16 mpgs? I'd be happy with that, do the payoffs of a lifted jeep heavily outweigh the negatives? Another factor is that there is a e85 converstion for the 4.0, so if we ever get a station around here i'd definately have no regrets. I'm a very outdoorsy person and have always wanted a lifted vehicle, for my adventures, is it as fun as it looks? Any input would be appretiated.
Also it is a dd but mainly only about 24 miles a day. This is planned for next summer project.

Any of you who have done a similar combo and daily drive it have any regrets whatsoever of doing so? Would you advise me not to? What do you recomend?

here she is as of now.
