Merge conflict resolution can be taught in a very small amount of time. It's not very complicated at all. If you're training a team who are new to version control, this will not take long and will avoid the additional training needed should the team crossover to git later. I'd stay a million miles away from training a team on SVN instead of git if I had an opportunity like this.
Also, please note, I'm not simply pro-git. If you really don't want to use git, use mercurial. I've used a fair few different version control tools in my professional career, and I'm a little tired of developers having to re-train and move away from svn when they could have started with the tool they have migrated to in the first place.
