Is it possible to grammatically combine two separate sentences Xがverb。Yがverb。into just one sentence Xが、Yが、verb。? For example,
料理ができる。掃除ができる。→ 料理が、掃除が、できる。
My original motivation is to understand the role of が in the more complex sentence:
ただ喜びと悲しみのあいだにある多くの事象が、その互いの位置関係みたいなものが、まだうまく見きわめられなかっただけだ。(村上 春樹. 一人称単数 (Japanese Edition) (Kindle Locations 23-25)
I found many questions regarding multiple use of the が particle in a sentence but to the best of my knowledge they concern the case in which one of the が is on a relative clause which I think it is not the case here.
