It depends on what you are prepared to spend.
Because BB height in a trike can be whatever you need it to be, and front wheel / foot overlap is not a massive problem, almost any length of seat tube / reach to the handlebars can be accommodated. It's better if front wheel overlap can be avoided, of course ... but not the close-to-necessity it is on a bicycle.
At Longstaff, we / they have built trikes with full-sized wheels with incredibly low BB step-over heights / saddle heights for riders with specific disability - it's not a low-cost thing to do - but nor is it the close-to impossibility it is on a bicycle.
As mentioned above, you kind of have to forget bicycles in trike-world. It's a bit of an adjustment to make!
