Why don't you just point Kodi to where your albums are and let Kodi add them locally, leaving your Twonky Media Server to serve them to anything else you might have connected ?

I've actually considered this when I started my "Noxon replacement project" (Raspberry Pi with standard 7" touchscreen) but rejected that option for multiple reasons:

1. the storage tree (currently 8,100+ songs, 622 artists, 605 albums, in 701 folders) would have to be accessed over SMB/CIFS, and enumerating that over Wi-Fi would take some time
2. I was unsure how taking updates (file changes, additions, removals, moves...) into account would work: would Kodi need to re-enumerate the tree periodically? At each start?
3. Navigating such a large tree using the standard Kodi UI is rather inconvenient: the top-level list in Kodi is the list of artists, finding a particular artist or album by scrolling such a long list on such a small screen is impractical. This is why I have configured TwonkyServer to serve several trees: by artist * / ABCDEFG / HIJKLMN / OPQRSTU / VWXYZ then AB / CD / EF / GH..., by album # / * ABCDEFG / HIJKLMN / OPQRSTU / VWXYZ then AB / CD / EF / GH.... you get the idea -- and UPnP only transfers the currently displayed list when navigating those trees, not the whole hierarchy.
