sure go for it... seriously doubt you can hurt it much repotting it, but it will survive in that current pot for a another few years if you want to... it would be better in a heavier pot, though, so it will be less likely to keep falling over.

Thanks for the feedback. It is really top heavy and essentially impossible to keep upright. I'll think I'll move it to a terra cotta pot with gritty mix tomorrow.

Essentially impossible? Not so....just use a thicker layer of top dressing and that problem's solved (or use rocks to stabilize).
