couple of points:
you need to be a bit more specific on the weapon.
one handed or two handed weapon? this also affects the max imbuing weight you have available.
should the weapon be able to whirlwind (since you want hit area on it)?
what's your stamina after you suit up? or in other words, how slow can the weapon be to still get to max swings with your stamina and 30 ssi?
100 life leech/mana leech are both mods that can only be gotten through runic reforging since they're overcapped and as far as I know you can only have one of them on your weapon, so you have to decide if you prefer life or mana leech.
having 5 mods on your weapon means you need to take off the damage increase that every exceptionally crafted weapon has. this means you need to farm up a whetstone of enervation. while this is absolutely possible to do it will increase the price for this weapon drastically because of all the hassle involved.
Also the combination of mods you posted above are impossible to fit on a weapon because they exceed the imbuing weight limit by far.
