PX4 Storm .40 S&W 10 round mag to 14 round

[Stormin.40]

I notice that you can now get a conversion spring and feeder plate to convert a 14 round magazine to 17 rounds, base plate extention. I have 2 17 round magazines for my PX4 Storm but would like to convert my 2 factory 10 round magazines to 14, I like the short mag profile for carry but would like the extra capacity. The skin of the magazines seem to be the same so I was hoping it would simply be a sprint/feeder plate exchange.

Anybody know if this is an option?

generally low cap mags are made so that they cannot be converted into standard cap mags, for use in commie states lol
10rnd glock mags for example have ridges molded inside so that a wide spring and follower cannot fit without milling out the inside somehow
