Hi!
Yes, sure.
MOST Editions of the games should work, but as to Baldur's Gate 1+2 I recommend the 5-CD (BG) or 4-CD (BG2) versions. Of course when you buy you usually do not know how many CDs they have.
"The Original Saga" Edition (on 3 media) also works (english version at least).
Also Computerbild Spiele 12/2008 GOLD Magazine DVD has Baldur's Gate 2 in Multilanguage edition (also works). Sadly the Addon Throne of Bhaal in this edition is German-only (but main game is multilanguage). Sadly Computerbild Spiele 12/2008 non-Gold edition (BG1) is German-only.
As to Gog if you bought enhanced edition there, you can go to your Gog library, then click the game, then on "More", and then on "CD Keys", there you can then trigger that you can download the classic edition (sometimes Gog runs out of cd keys, I had to email their support and wait a few weeks to get my classic edition - they are in meantime aware that Amiga users might be interested in that stuff though - I explained to them ^^). Note Gog version comes as windows exe and needs preinstall.
But basically most versions of the game should work. Ah, BG1 6-CD-Edition English Version works too.
The port was 20% Game-porting and 80% adapting the installers to all sorts of different versions (some betatesters were very active in sending me textfiles of file-lists of non-working versions

)
If you end with a version which does not work, just email me to
tirionareonwe@gmail.com and I will adapt the installer so it works with your version too (as far as possible - I can adapt all versions which contain a "cab file" (data1.cab or such). The ones with huge exe files do not work, but most versions have the cab files, so normally (nearly) all should work.
Stay away from anything called "LegendsRPG Edition", for those BG1/BG2 does not work (they use exe files). Not sure if LegendsRPG was only for Polish market or also english version.
If you have the data from an install on a PC you can use that too - transfer it to Amiga, then run the Gog Installer (no matter if the data from PC was installed via gog or not) and when it asks about "Gog Data" just point the installeer to the transferred data. That works too.
If you have still questions feel free to ask (or to send me screenshots of the cover of the version you think about buying, if I see the cover I can usually tell if this one works).
The "good versions" are usually somewhat 1998-2002 or whatever, of all four games.
Fine working are
Baldur's Gate 1
Baldur's Gate 2
Icewind Dale 1
Planescape: Torment
The Addons (Tales of the Sword Coast for BG1, Throne of Bhaal for BG2, Heart of Winter for IWD1) will also mostly work, but might have a few "issues", while the main games will work completely.
If any questions left, feel free to ask!
