I think the need for currency can be overstated. There are lots of things which probably shouldn't be done if you're not current, like flying in bad weather, flying through complex airspace, flying with additional pressures (nervous or inquisitive passengers, time constraints, etc), flying a new type, flying a particularly complex type and so on.
But let's say you've not flown your 172 for a couple of months. If you approach an easy flight say to an area you're familiar with, in good weather, use your checklists, etc. what's the worst that will happen? You might forget to retract your flaps after take off (so what?), you might fluff up your radio calls (so what?), you might not do the smoothest landing etc. However, if you keep fuel flowing to the engine and watch your airspeed I would imagine that your basic training will take care of the rest (i.e. keeping it the right way up, pointing in the right direction etc.).
On the other hand, if you ask around I'm sure you'll find a local pilot willing to sit in the other seat to keep an eye on you.
