Folk instruments for tuning in fifths? Or tips for acoustic gtr?

    Hey, everybody. I'm new to the group. Explorer already knows of me, as I posted a question he answered yesterday.

    Anyway, I hope this is the right place to ask this question. I noticed some photos pinned to this group that have some Iberian folk instruments on display. I'm curious if anyone knows, before I put the money down for one, if something like the viola amarantina, viola da terra, or viola caipira could be successfully tuned in fifths. I'm determined to find an instrument with a guitar-ish tone that I can tune CGDAE. If I could get a sixth string tuned to B, that would be a bonus, but I could settle for a five-string (or five courses of strings) that would still have the range of a standard-tuned six-string acoustic anyway. If I could find a five-string tenor guitar, that would be fine too, but so far I've found nothing, and my budget precludes having a luthier make a custom instrument for me.

    Barring any of that, if I managed to convert a six-string acoustic to fifths, is there an ideal scale length and/or string gauge I should be focusing on? It seems that with a bigger guitar, the C2 would sound good but the B4 would be more prone to snapping, but with a smaller guitar, the B4 might work at a small string gauge but the C2 would be floppy and mushy.

    Any thoughts are welcome. And forgive me if I'm saying anything stupid. I'm a rookie when it comes to stringed instruments, but I know enough to know what kind of tuning I'm after. Thank you.

    it is late but..... the violas portuguesas have short scale length dificult for 5 courses in fifth ... the same applies to spanish la˙des so most used tunings are in fourths o close to it..... The viola caipira from Brazil has a longer SL that goes from 58 to 61 cms that is able to hold fifth tuning using octave stringing for the coarser string ... so the neck may hold it without trouble...
