| Do multiple passes of guitar and vocal and comp between them. This can be somewhat challenging if the takes are not done to a click.
If you must replace a line with an overdub, you'll have a better chance if the phrasing of the overdub and the line you are replacing is the same so that the vocal in the guitar track won't conflict too much with the overdub.
You could also do a pass of guitar only and use this to cover the moments you need to overdub. This will work fine unless this is a strictly solo performance - if it is a solo, the ambience change may or may not cause problems. If the performance is part of an ensemble you should be able to make it work.
