Starfinder to PF2 Conversion Concept

So, I really want to run Starfinder games on the same rules chassis as PF2. I'm dissatisfied with quite a lot of Starfinder's baggage, so I've put together a proof of concept document to feel out my approach for porting over the minimum amount of things from Starfinder to PF2.

In the link below, I have a proof of concept attempt at converting the following:

Classes
Ancestries
Technological Weapons, Armor, and Items
Technological Skills
Starship rules

I would be very happy if I could get some feedback from you kind folks about these approaches. If there are any serious pitfalls you predict, or modifications you would suggest. I'm also open to hearing if it's all just a bad idea!

I like it, and i trying to covert some races to Pathfinder 2e too. Like, the Dragonkin, from Alien Archive.

Any suggestion of how do that?

So, my approach with converting races from Starfinder is:

1. Convert basic mechanics and adjudicate relative strength

For most races this part is pretty simple:

Dragonkin
HP: 10 (The high value, similar to 6 in Starfinder)
Size: Large (With reach)
Speed: 25 ft
Ability Boosts: +2 str, free (+4 str isn't an option, dropped to +2)
Ability Flaw: -2 dex
Senses: Darkvision

So, being large with reach is nutso powerful. So much so, that I think it's fine to leave off one ability boost. The above would still be too strong, because it's basically a dwarf+ for any melee character. Interestingly, being large without reach is actually neutral or slightly negative. You can't be pushed or grappled by small creatures, but you can't fit or hide anywhere, weigh more, are more easily flanked and attacked by more enemies, and make for a big target.

In order to have room for the rest of the powerful abilities from dragonkin that would come in as very good ancestry feats, we're going to have to trim it down.

Dragonkin
HP: 8
Size: Large (Without reach)
Speed: 25 ft
Ability Boosts: +2 str,+cha, free (+cha for draconic-ness)
Ability Flaw: -2 dex
Senses: Darkvision

2. Create heritages with the most powerful/flavorful leftover parts.

Strong Wing Dragonkin: Can fly 25 ft, but must end movement on the ground or fall.

Breath Savant Dragonkin: Gain a breath weapon focus power.

Bond Trained Dragonkin: Gain bond with one creature, which grants telepathy and initiative bonus to partner.

3. Create feats which let heritages dip into one another, and fill in any further missing race traits.

Lvl 1:
Flight: Can fly 25ft, but must end movement on the ground or fall. If you selected Strong Wing heritage, you increase the fly speed to 30ft.

Breath Weapon: Gain a breath weapon focus power.

Bond: Gain a bond with one creature, which grants telepathy and initiative bonus to partner.

Draconic Immunities: If you roll a success on a saving throw against a sleep or paralysis effect, you critically succeed instead.

Lvl 5:
Improved flight: You don't need to land after every move action to fly.

Lvl9:
Growth: You gain reach as per a normal large (tall) creature.

4. Fill in the rest of the feat list with feats of moderate strength poached from other lists

Lvl 1:

Dragon Lore: gain trained rank in Arcana and Religion. You also become trained in Dragon Lore.

Lvl 5:

Flight Elocutionist: You can communicate in a limited manner with animals that have flight speeds, such as birds and bats.

Lvl 9:
Cave Climber: You gain a climb speed of 10 feet.

Lvl 13:
Iunno man, we gotta wait for more ancestry feats to get printed. The weapon expertise chains could get added into any ancestry with some modifications I guess.
