So I had this really odd idea.

Let the following be true:

X = base ranged weapon speed
Y = max mana with normal gear
Z = the amount of Intellect gained from two caster-oriented one-handed weapons enchanted for Int

When you run LOM, you jump into Viper, then throw on your weapons defined in Z.

Mana = Y + 15 * Z
Extra mana gained per shot = (15 * Z) * (X * 2 / 100) * 1.10 (Glyphed)

Theoretical: X = 2.80, Y = 8500, Z = 156 (90 from enchants, 66 from two Saronite Spellblades)

Mana with the blades: 10840
Target mana: 8500
Mana per shot: 667.744
Shots to Target mana: 12.7-ish (so 13)

Mana without the blades: 8500
Target mana: 8500
Mana per shot: 523.6
Shots to Target mana: 16.2 (so 17)

Is making 13 shots weaker while in Viper worth getting four more normal shots out of Viper? Only time will tell. But I really think it's... at least worth looking into.
