I would have to kinda agree on this. So his shirt is "Death" stating "I'll be here if you need me". So when you think of the magus sisters, they are an aeon or summon technically that you were able to use. This could fall in with the "I'll be here if you need me". As for "Death" itself we associate a scythe. Cindy uses a scythe. Also here is a snip of "lore" ---

"Magus Sisters may be a reference to the Moirai, often known in English as the Fates. The Moirai were the three incarnations of destiny—Clotho (spinner), Lachesis (allotter) and Atropos (literally 'unturnable' but metaphorically 'inflexible' or 'inevitable'—i.e. death)"

Also the Magus Sisters first appearance was FFIV. And what is Endwalker based off of heavily? FFIV. Where do you first fight the Magus Sisters? In the Tower of Zot or in FFXIV instance - one of the Spires that Fandaniel constructed. Although in FFIV it says the Tower of Zot is only accessible by the "Enterprise" because it is speculated to be floating in the sky (Or maybe on the moon?) As for the "Enterprise", in the Endwalker logo that "ship" or w/e it is that we see could be the "Enterprise" we use.
