Definitely possible, but all facility upgrades, including ground, take enormous amounts of cash assets.
Currently in my first season in league 1 with Alfreton (5th season overall), and we're still using a 3600 capacity stadium. Lol. Hoping we can make enough money to get a bigger ground soon.

OMG just got a stadium expansion!!!
Unfortunately it's only 920 more seats (3600 to 4520 total). LOL I think this may actually hurt us more in the short run than help us.
