Which is why two of my goto magic mods have summonable inventories. Deep Storage for Apocalypse: Magic of Skyrim, and the Midas Luggage from Midas Magic. (Sadly Midas is only available for Oldrim.)

I've done stealth archery... it's very strong, but I find it so boring. I much prefer stealth melee. Sneak up and hit them for 15/30x damage.
