Yes is it possible. The VPS server depends on how big and how scripter your gamemode is. The mapping itself wouldnt change anything too much unless its a huge ass town with milions of objects. Of course, make sure you are using streamer for those objects.
And if you are doing a big town, you would need some security measures so they dont fall thru the objects due to loading issues that might happen and so on.
