To me that's a good shop. Instead of blindly follow a curriculum, they'd listen to the customer and see what they can do to meet that customer's wants and needs without having to sacrifice the education.
Of course, the issue is always one of whether the student's "wants and needs" are remotely reasonable. With zero "tech" training to date and not a lot of dive experience (<200 dives), what makes you certain that your "wants and needs" concerning decompression and trimix are good ones? They very well might be, but do recognize that agency and instructor standards exist for a reason. I'm going to assume most divers already doing the types of dives you want to do have a better sense of what might be required to do them than the tyro.
