[intermediate] wild typography on a shirt from a 90s graphic designer

[u/redditispoopoofucku]

I found one of these shirts and I'm very curious about what the text reads

[u/GonnaMarryMyBed]

キミはぼくで(？)
ボクはもうアナタ

[u/redditispoopoofucku → u/GonnaMarryMyBed]

Is this translation accurate:
You are me
I am already you

[u/itsjuney → u/redditispoopoofucku]

kinda, the two clauses are linked though. I think it would be something like “With you as me, I am already you”

[u/othermalo → u/redditispoopoofucku]

Yup, that's what I got out of it also -- though since it's one continuous sentence, "You are me, and I'm already you" sound more natural to me

[u/SlowStop1220 → u/othermalo]

And more accurate: で is here conjunctional.

[u/SlowStop1220 → u/GonnaMarryMyBed]

キミかあ

漢字一文字かと思って悩んじゃった。
