custom or upgrade

So recently my shoulder has been getting better from my little accident in march. So i have been slowly going off road on different surfaces to get my confidence back up to where it was prior to my over judgement. I am 6'3 and standing up on this bike im hunched over like crazy. The bars even with the cr highs are about 6 inches to low for me to comfortably stand up. My delema is that I love the bike suspension and engine wise but the ergonomics for me aren't there. Would it better better to look at a bigger bike like a drz or spend the money to get the ergos to fit me? On road the bike is perfect for me right now but just standing off road is a no go.
