You could do that, but it won't be cheap.
You'll need a new crankset and bottom bracket, cassette, chain, shifters, derailleurs and rear wheel. You'll have to cold set (bend) the rear drop-outs to accept the new wheel. The parts cost will be way more than you could sell the bike for. You'll do better buying a bike with the gearing you want.
How far off in gear range are you? If it's just a bit, changing the small chainring to 39 tooth may be enough, that's easy and quite cheap. You also just get a triple, probably need a new BB as well.
If you stay with friction shifting you could avoid replacing shifters and derailleurs and go 9 speed. Still need new wheel, cassette and chain.
