There's nothing wrong with taking a traditional system, and incorporating elements of other systems into it. After all, Ohtsuka Hironori did this when he started the Wado system, by mixing Karate with Ju Jutsu.
It's not really about what systems are mixed together, but rather a matter of whether or not the instructor is any good.
Of course in Ohtsuka's case, he was already an expert before he started his Karate training... His situation was hardly the same as the guy who trains at one school for a few months, moves onto a different school and trains there for a year, then goes onto another school and trains for a few months, etc.
Remember, there's a difference between having 10 years of training, versus 1 year of training repeated 9 times.
Pretty reasonable positions.
I'd observe that it is important that the public be told exactly what they are getting. Too often they aren't, or are actively misinformed.
There have been some excellent discussions over on the CMA section on chamges to systems. Innovation and improvement are necessary, I believe.... but others have made the sound point that the amended style should not be passed off as if it were the original.
Some CMA practitioners would differ with you on your last paragraph. They seem to feel that Americans, hungry for superficial knowledge, run through forms too quickly. Tradition would appear to favor more of those repeated training years.
