Rachy, I'm honestly not sure. The "reasonable" would have to mean acceptability in society. I've been a reenactor for nearly 20 years and I'm well acquainted with the interesting reactions I get in "normal" spaces. I also do costuming (i.e. dress up in costumes and Do Things), which also garners lots of comments and questions. To be honest, I don't dress to blend in much even nowadays... but 18th century, Jane Austen, or Edwardian is a lot more strange and noticeable than that.
If public attention and suitability wasn't a factor... yes, I think I would. But just like now, I would not limit myself to one particular style or historical period, and I might do it only occasionally. Regency (i.e. Jane Austen) is by far the easiest and most comfortable to wear, even with stays. It's also the easiest to move around in. So I'd probably spend most of my time in it, if not my present style. But 18th century (esp. 1780s) feels really awesome, with or without a wig. (Wigs: Easiest hairstyling ever. Followed closely by caps and bonnets.) I'd probably rearrange the furniture in my home to wear 1860s hoops easier, but it's also lots of fun to swan around in. Apart from the number of pieces it takes, it's arguably the most comfortable. (Also fun to do unexpected things like sprint when necessary, or sing soprano!) And I would love to go a LOT more 1950s and 1940s than I usually do; big fluffy petticoats are awesome even at an office desk. There are plenty of other eras I want to play in and just haven't gotten around to making yet, and I have an awesome reproduction shoe collection that definitely needs more wear.
But I would also have to rearrange my schedule a bit (in addition to the furniture). Getting dressed in these things does take more time, not even because they're complicated; it's just more pieces. Exactly how it takes me longer to get dressed in winter than summer.
...That's probably a whole lot more answer than you were looking for! :p
