If you want a really good simulation:

Most likely foils and non-foils are keeping the same rarity distribution, so for simplicity of calculations we can omit foil slots for now.

To open one of each mythic, you need to open 140 packs. This also gives you 2 of each rare. 280 cards total.

140 packs is 3140=420 nonfoil uncommons and 8140=1120 nonfoil commons. 5 copies of each common and 12 copies of each uncommon is 400 and 1092 cards, reasonably close.

This gives a huge cube of 1772 cards. To have good amount of foils, you need 2/15 of the cube to be foiled. So about 5 mythics, 32 rares, 54 uncommons, 146 commons.

Of course such cube is big and expensive. And not really the best it could - 2X2 has a lot of rares and mythics which are there only to be reprinted. Worst offender probably being [[Thrumming Stone]]. My plan for this cube is:

Cut one colorless common I don't like. Take 6 copies of all others. 540 cards.

Take 3 copies of each uncommon. 240 cards.

Take 1 copy of 120 handpicked rares, some from this set, some not, chosen to fit the cube. 900 cards total.

Add 60 copies of the fixing land. Have packs of 9 commons, 4 uncommons, 2 rares, 1 Cryptic Spires. Start playing and testing, amending if needed.

Added Saruman of Many Colors just for something fun. Not sure if playable yet.

Chose:

Stitcher's Supplier to replace Shadowborn Apostle

Also removed Dark Supplicant. Not Enough Clerics

Removing Shadowborn Apostle for either of these:

Plagued Rusalka

Stitcher's Supplier - Chosen

Nested Shambler

Shambling Ghast

Reddit Comment answering good Black one drops:

[[Bloodsoaked Champion]], [[Cult Conscript]], [[Dread Wanderer]], and [[Gutterbones]] - My recursive aggressive black one-drops, great for bridging the gap between various aggro and graveyard strategies.

[[Carrion Feeder]] - Classic, free sac outlet for one mana that enables loops and shenanigans.

[[Cryptbreaker]] - [[Pack Rat]] was a little too powerful for this environment, this guy does a nice impression.

[[Deadeye Tracker]] - Graveyard hate on a stick. This might be too slow to keep around, hasn't been tested much yet.

[[Nested Shambler]] -Two bodies to sac for one, plays great with +1/+1 counters, combat tricks, and equipment.

[[Plagued Rusalka]] - Underrated unassuming little card. Keeps your opponent off board in aggro and aristocrats mirrors.

[[Shambling Ghast]] - One of the best aristocrats one-drops, its flexibility gives it a lot of homes.

[[Stitcher's Supplier]] - Signal for people who want to go deep on the self-mill themes in the cube.

[[Viscera Seer]] - Like Carrion Feeder, a free sac outlet for one mana that enables loops and shenanigans.

Added Siege Rhino for fun as a rare (As of now 21 cards left to officially complete the cube) Rares not owned are proxied for now

Added Dark Supplicant in the common slot. I don't like the Shadowborn Apostle but I haven't removed them yet. Just wanted to see how this worked. 

As a Backup I like Archfiend Vessel.
