Should I take off my braces early to get porcelain veneers?

I've wanted veeners for a really long time and am finantually able now to get veneers. I want to know what the repercussions would be if I took my braces off early to get veneers. I've had them on for two years and am supposted to have them on for another year but I don't know if I can wait that long. I've had troubles with the way my smile looked for the longest time so the sooner the better but I won't take them off early if their will be negative consequences that will affect my smile more
