I reccomend using ImgBurn to firstly build an ISO of your vobs and then burn that same ISO with imgburn to a DL disk. Imgburn handles the LayerBreak much better than Nero and the like...
Here's how to build an ISO in IMGburn...It's by a great guy called arniebear from AfterDawn...

Then to burn it you merely switch to burn mode.
And to answer your question, no it wouldn't. Are you really telling me that switching between SL layer disks is easier than one DL?! And maybe slightly more expensive, but just dont use them like they're going out of fashion. Just for the good films etc...

Just that personnally i don't find it a big deal to throw in 2 DVD's for the same movie, I realize that perhaps many folks do not like to do this.
Is there a way to backup my DVD's on the Dual Layer media without it screwing up the movie? Every Time It seems i hits that layer break I am guessing the dvd player lags out...
