I think we should be snatched as level 15, fully equipped adventurers in our chosen class - and the Ilithids pop us - fully equipped - into the chambers.
And they should also snatch up our best adventuring buds, also fully leveled and geared, so we have our preferred comrades in arms with us.
And they should have a chest with a dragons treasure hoard conveniently waiting to be looted.
And be sure to crash right next door to Elminster's Enchanted Equipment Emporium and Discount House of Worship Gear - while a sale is going on.
And almost forgot - just before he dies by Demon, the head Ilithid should spout out his entire evil plan in detail, including all relevant allies, steps, goals and timelines.
And Drizzt should stop by with Baby Yoda in tow, because...Baby Yoda!!
Hey, if that's what you want, I'm sure there'll be a mod for it. I don't think most people want that but y'know, you do you friendo.
