Of course it is possible!
I've upgraded my pledge. I was a beta backer and now I'm an alpha backer.
Is it worth upgrading? Well, it depends on which tier your are right now. There is no point on going into developer access level now when alpha should be released in month or two* (*my own estimates). Unless you really want to.
If you can afford it, if you don't want to wait, then go for it.
Is it possible to increase my donation amount? Or not possible/worth it?
