Non-standard equipment can have it's advantages and it's disadvantages. If you decide on non-standard equipment be prepared for supply problems, extra costs, or make it yourself. Your Choice.
I can't begin to contemplate all the "great" new ideas I've constructed, tried, and either discarded or kept over the last 50+ years of beekeeping. I'm still dreaming up new equipment that I build and try. My latest is a 12 quart/pint jars hive feeder that I can also use for comb honey production. One of my earlier ones was a slatted rack using 5/8 or 3/4 dowling instead of flat slats. I still prefer and recommend that style of rack over the commercially available ones, but using them requires I make my own.
I decided on 8 frame hives because they did the best job of what is considered a standard size that is readily available. If I were going to re-invent the wheel, making new version of a Langstroth hive, I would make the hive boxes and frames to fit a 14 inch cube.
It doesn't hurt to maintain a DE hive, an 8 frame, a 10 frame, or even a 12 frame, if that is what you have. It is fun to compare 1 type of equipment against another. It inproves you beekeeping skills and will lead you conclusions and ansers that other beekeepers don't even have questions for.
