I seriously doubt a novice could do a custom design just from a few tips on an internet forum if they don't have the experience. Unfortunately the correspondence here does not seem to be up to the level needed to complete this task safely and appropriately.

If there is added support in the form of blocks below the mass area, the original structure is not being asked to hold all of it. Floors are required to be able to support a concentrated 200 lb load at any one inch diameter spot on the floor, so as long as the joists are supported, the flooring should be able to transfer the load to the joists and then to the new blocks.

Wrap up with scarves and hats inside. It may seem strange, but it really helps to conserve body heat. Wear a hat to bed! Everyone gets a hot water bottle for both day and night time use. If it's cold during the day, I'll keep one on my lap as I knit/read/etc. I take it to bed with me in our unheated bedroom. My son too, but his dad doesn't usually need one, although he sometimes borrows one of ours. I refresh it with hot (not boiling) water from our electric kettle as needed. Go out during the day to a heated public/community space like the local library. Or make a visit to a different neighbor every day. Anywhere warmer than home Go out for a brisk walk; I walk my son to and from school every day and am warm for the next hour at least. Send the kids out to play a rough/noisy/vigorous game. Hide and seek? Tag? Have hot meals if possible. I eat a hot breakfast and dinner, but really notice a cold lunch in a cold house. Breakfast for me is scrambled eggs, and dinner is usually in the slow cooker, so not a huge time commitment either way. I need to figure out a quick hot lunch, I think. Warm up in a hot bath right before bed; for us, it's more of a soak than anything, as we're no-poo (no shampoo) and mostly no-soap. Usually my son gets in first, then me, then my husband. We don't empty the bath until the last person's done--although if we get in and it's too cool, we'll let a little out then add more hot. In the summer when we actually get sweaty/dirty we take our own showers/baths, but in winter the water stays pretty clear especially without shampoo and soap in it. I don't let my long hair get wet (I've gotten to the point where I only wash my hair with water about once or twice a month) unless the house is warm too--but short will dry quickly enough. I guess blow drying is an option.
I recently built my very first RMH (a batch box with masonry bell) myself; my husband was recovering from surgery and my son is seven, so I really did it all by myself, complete novice that I am. It's not pretty, and it took me three weeks and some frustration, but if I could do it, I'm sure you can too.

I'm thinking that it might make sense to just start with a rocket stove and skip the "mass" part of it at least for now. The reason being that it best matches the above goals. You might want to start with the hardest part (and could be the most expensive part) which could be figuring out how to safely install a flue/stack/exhaust to go through the roof (or wall). There are some youtube videos on this.
