So, the ConfigConverter looks like the way to go for me, therefore I'm attaching all three files you mentioned.
@Solarius
1. open Mapview2
2. goto Edit|Configurator
3. select XCOM Resource paths
4. set UFO to "D:\ufa_zapasowa\UFO" (no quotes)
5. set TFTD to "D:\ufa_zapasowa\XComTFTD" (no quotes)
6. E=mc^2
7. let Mapview2 restart, then close it.
8. in subfolder /settings, rename your current MapTilesets.yml (eg, MapTilesets_bak.yml)
9. drop in the attached MapTilesets.yml
10. open MapView2 while doing a voodoo chicken dance
Notes:
- changed the duplicated "XBASE_05" to "XBASE_06" (which was missing from the sequence of XBASE_0*)
(group: UFO - Terrain, category: X-Com Base Expanded)
- deleted the duplicated "XBASES00" to "XBASES03" (but no maps were missing from the sequence)
(group: TFTD - Terrain, category: X-Com Underwater Base)
- warning regarding "LINERT0*" - the terrain "DECKC" is assigned twice on each Map (left as-is)
(group: TFTD - Terrain, category: Cruise Ship 1 Terror Site)
- changed terrain "plane" (mcd/pck/tab reference) to uppercase "PLANE"
- tilesets that exhibited anomalies during the conversion (terrain variables were redefined between UFO and TFTD):

To edit a tileset, select it in the maptree, right click -> Edit Tileset ...
[F1] should open the Help file
there's also a keyboard_cheatsheet.txt
If we're lucky this will work first go, but I suggest just browsing around (in Mv2) for a day before doing serious editing.
oh, and back up yer stuff ! as in ... now (plsktks)
