Got my mind set on 26 def, so had to do a bit more "theory crafting" and my end QP will be ~220ish IIRC, and here are my end stats needed to complete all possible diaries with 26 def, and all possible quests with 26 def. Along with additional reqs for stuff I'll need
50 range (passive 99 via slayer)
68 farm (passive 99 farming all seeds, need to be able to plant torstols)
54 mage (66 quest passive 99)
50 atk (99 via slayer)
42 slay (93 for occult necklace)
66 hunter (83 d imps)
48 herb (57 quest passive 99)
50 con (83 jewellery box)
59 smithing (74 adamant darts)
59 fletching (95 dragon darts)
40 crafting (50 quest, 85 fury)
40 mining (50 quest, 61 dragon pick)
47 thieving (53 quest not sure how necessary master farmers are going to be, but might just train 53+ on master farmers while getting seeds)
70 combat (107 maxed cb)
23 runecrafting (unsure atm, I want to try and avoid this skill as much as possible)
52 prayer (passive 99)
60 woodcutting
These are just additional skills that aren't needed for diaries/quests
strength (passive 99 via slayer)
defense (26 all through quest)
