want to keep your original hub here is a 9 speed FREEWHEEL
so here we go 9 speed freewheels exist , made by sunrace , intended for use on E-bikes but they have the shimano thread type so they work on normal hubs!
saddly they are only 13 tooth small gear, no 12 or 11

Almost any late era 7-8 speed hubs. I have a couple of Sachs New Winner hub sets that are 130 spaced.

I guess you can hope they start producing a freewheel that's 13-14-15-16-17-18-19-20-21. It's a modern corncob.
But seriously, folks, this is a bizarre development. I don't see the point.

I built corncob freewheels out of a couple cheap Shimanos and some loose sprockets. It was easy, and fits my riding style exactly. 13-14-15-16-17-18-28 for my ergo compact and 13-15-16-17-18-34 for my 39/53 DT shifters. Had to use the dremel for the 7 speed.

cudak's right, you'll be bending axles left and right unless you're a featherweight
honestly though I could dig a 13-14-15-16-18-20-22-26-34...and just a 50 up front. Maybe its time for me to start fiddling with cogs.
whats out there as far as like a 7 speed freewheel where you can swap all the cogs around?

you could do it with a vintage RD and friction shifting if you wanted although I'd bet the shifts would be really close together.

I rode my Sachs for a year and I am not featherweight. Axle still straight even with some railroad jumps. Now I don't think I will be taking it out on tour but they aren't all that fragile if you have good quality under you.

Yes, but they are 7-speed, at most.
Single chainwheel bikes aren't the panacea they look like on paper. Chainline gets to be a problem. The front derailleur, even when you don't use it, serves to keep the chain on the chainwheel. Take it off, and you have more mishaps.

I have an 8-speed freewheel in the parts bin that I'm not using for fear of breaking an axle. I'm not a heavyweight, but it just seems like a bad idea, and that's why cassette hubs were invented!

Same as an 8-speed FW, they both require a 130MM spaced axel, resulting in a longer overhang from the bearings to the frame, more likely to bend/break the axel than if 7 speed at 126mm. I had way to many nice 7-speed hub wheelsets to just throw them all out when I finally converted my race bike to 8-speed in the early 90's. I set a few of my race wheelsets up with 8-speed freewheels and had no problems when I used them just for road racing while using casette hubs on my daily training wheels that were subject to more abuse and miles. One adaptation I also came up with was to put a 30mm OD sealed bearing toward the frame end of the axel (on a "cone" from a sealed bearing hub). THe OD of the bearing fit right inside the outer small cog of the freewheel, giving the axel some extra support.

At some point I'd like to upgrade my Voyageur to 9 speed but keep the 27" wheels. It's not easy to find a 9 speed compatible, 40 hole hub without going real expensive (phil wood, white industries, etc.) or using a tandem hub...which isn't much cheaper. This at least provides another option, and at a fraction of the price (~$20 vs ~$150) of getting a new hub.

BTW, If you have to go to 130mm, I'm betting you'll have to redish the rear wheel because it won't be centered. I know when I changed my 7 speed freehub to 8/9/10 on the C'dale, I had to re-center the wheel. I'm guessing the same is true for a freewheel conversion.
