Zen Archer + Ki Arrows + Gravity Bow = does it work?

[Dahbadu v2]

*Zen Archer + Ki Arrows + longbow 1d8 arrows -- how does it work?*

For example...

I have a longbow that has 1d8 base damage for its arrows. I'm a level 4 monk. My base unarmed damage is 1d8.

If I used Ki Arrows, would my base damage remain 1d8 per arrow (as my unarmed damage isn't higher)? Or would it be higher? If so, what?

*Ki Arrows + Gravity Bow -- how does it work?*

For example...

I have a longbow that has 1d8 base damage for its arrows. I'm a level 7 monk. My base unarmed damage is 1d10. I am also enchanted with the Gravity Bow spell.

Let's say I use Ki Arrows to increase my base longbow arrow damage to 1d10, which is my unarmed damage. Would my arrows do 2d8 damage each?

*Ki Arrows + Gravity Bow + Enlarge Person -- how does it work?*

For example...

I have a longbow that has 1d8 base damage for its arrows. I'm a level 7 monk. My base unarmed damage is 1d10. I am also enchanted with the Gravity Bow spell and the Enlarge Person spell.

Let's say I use Ki Arrows to increase my base longbow arrow damage to 1d10, which is my unarmed damage. Would my arrows do 3d8 each?

That's 1d10 > 2d8 (Enlarge Person) > 3d8 (Gravity Bow?

Please advise.

Your ki arrow ability allows you to substitute your unarmed damage for your regular arrow damage. When you enlarged cast on your self and you use a ranged weapon the weapon shrinks back to it's original size. Gravity Bow spell increases one die step. Maybe you can stack ki arrows with gravity bow spell but not enlarge spell.
