In C2, not really. C3 will hopefully address this, but that's a long way off.
The usual method of merging is to firstly, ensure that all of the objects that are referenced by the Events exist in the other project. You can do this by creating a new Layout and just copying and pasting the Objects from one Project to the other.
Any Globals referenced would also need to be copied across.
You should then be able to CTRL-C - CTRL-V Event blocks across. If you get an error, it's usually because the Events are trying to reference something you haven't copied across.
Sounds a little long-winded, but it only takes a few minutes with practice - much quicker than re-coding from scratch.
