There's something about a flight across empty country in a tiny, underpowered plane that's simply magical. I highly recommend it...the rewards are, for some reason, higher than for those who fly larger, more capable birds. That said...
I assume you're flying solo. If not...er...I guess I don't recommend it. I really don't think crossing the Sierra's is going to be that big a deal. It's a short trip, even in a 120, and if you're not too heavy I don't think you'll have any problem, so long as you pick your day and time.
I'd be a lot more focused on the country east of the Sierra's. It's big, it's hot, it's a convective playground, and it's vivisected by a seemingly endless series of high mountain ranges that run north-south. Weather forecasting and reporting typically sucks. Radio communication and flight following are usually unavailable at the altitudes you'll be able to reach. Fuel stops are few and far between, and they are often higher (DA) than the Sierra passes you'll fly through to get there. You can't get to where you're going in the cool of the day unless you have a lot of days or you're willing to fly at night. Big chunks of any given day might be only suitable for flying a hammock.
I'm sure you can do it, but it requires some very careful planning, and the Sierra's aren't your biggest challenge. Fuel stops need to be researched ahead of time...a down pump can easily stick you in nowheresville for days. Cardlock fuel is not the norm, and lots of towns simply don't offer fuel on Sunday. Be prepared to sleep under your wing...even plan on it. Weight is a big deal, especially with all the water you should be carrying with you. Climbing to cruise altitude typically involves half an hour of circling a hill next to the airport, as climbing enroute over the playa is impossible.
With limited fuel capacity and anemic climb performance you inevitably end up doing heroic climbs to clear terrain, only to descend to the next fuel stop without getting any of the mileage out of your hard earned altitude. Military air space conspires to make direct-line flying impossible and deviations for weather loathsome...plan accordingly.
After my sixth trip across Nevada in a Cessna 140 I finally had absolutely no doubt that in the event of a forced landing, I'd never be found, flight plan or not. I bought a PLB and now consider it essential equipment for crossing the Great Basin. You should too.
On the plus side, flying across the Great Basin is a real treat. Just do all your homework before you go, pack ultra light, and give yourself plenty of time. You won't regret it.
