You can't launch HPR where I launch
You can't launch HPR why? Is it because you don't have a waiver? Or because there are no HPR cert'd fliers in your club to run an HPR lunch? Or some other reason?
Keep in mind that you can fly a handful of HPR motors, including some H's, under FAA LMR rules - ie, without a waiver. Only FAA notification is required. (IE, you tell them; you're not asking for permission; you don't need it.)
These would be motors that are 125g or less in propellant weight in rockets weighing 3.3 pounds or less fully loaded. Of course, you will still need HPR cert'd fliers to conduct the launch (at a sanctioned event) but it is possible to fly and cert HPR at an otherwise mid-power event.
The AT H128W, H165R, H238T, H180W, H210R and H220T are some examples that are under 125g. These would use the 29/180 and 29/240 cases.
Cutting things even tighter, you can fly and cert HPR without FAA notification if your rocket's 1 pound or less fully loaded AND your propellant mass is less than 113g. The H128W, H165R, H238T and H210R fit this requirement. It's possible. People have done it. The only catch is that you need to build real light, and have really good eyes, 'cause it's going way up
Maybe I'm not really understanding your needs, but what you've described is HPR that can be flown at LMR events, and this is how you do it.
