I was thinking of doing the same, upgrading my module to a Mimic Pro and switching pads over time to the Laurin pads. After giving the Strike a second look, and after seeing some of the features in action, especially the sampler, I think I've about got myself convinced to stick with Alesis. I can upgrade the entire kit for around the same price as the module by going with the Strike.
I don't know how the acoustic sound of the Strike pads is, but they're made differently from the DM10's pads? Maybe there's some difference in the acoustics, also, but to be honest, it's not really a selling point for me since I'm using it with my band. The DM10's acoustic noise hasn't been an issue, even with some of our quieter songs.
