I did one of these a few months ago. Six wrapped bichords on the low 
tenor with no bridge changes and no other scaling changes. It made a 
considerable improvement in tone quality at the break. Adding a few 
hitch pins is no problem if you don't let the owner watch you drill 
holes in the plate. Leave the un-used tuning pin of the original 
trichord in place, rather than an empty hole, and replace the 
agraffes with bichords.

A number of us offer scaling services, and can do this.

Inharmonicity isn't the problem with that low tenor. It's tension 
and low break%. The speaking lengths are just too short for plain 
wire at the required pitch.
