It will gain you 25 EP compared to 1 upgrade with a basic snakeskin. (cost: 3,000 + >12,000)

2 upgrades with 2 snakeskins will cost you 2 * (3,000 + > 12,000) = (only) >30,000.

At level 50 this strategy will cost you instead of gain you. Although using silver star armour for fusing will get you some time gain, cost wise this method will only be advantageous once the upgrade price per slot reaches 20,000. That will be around level 60.

In that case the cost for fusing and upgrading to 50 EP is:

500+500+25,000+20,000 = 46,000

and upgrading with 2 snakeskins in 2 slots will cost:

3,000+3,000+20,000+20,000 = 46,000.

If you use gold star armours to fuse the slot price has to be higher.

You can construct a formula for the break even point:

The cost of a 50 EP upgrade is:

with fusion:

Cost(upgrade) = Cost(armour1)+ Cost(armour2)+ 25,000 + Price(slot1)

with 2 snakeskin and no fusing:

Cost(upgrade) = 3,000 + 3,000 + Price(slot1) + Price(slot2)

So you want to fuse when

Cost(armour1)+ Cost(armour2)+ 25,000 + Price(slot1) <  3,000 + 3,000 + Price(slot1) + Price(slot2)

We can simplify that by taking out Price(slot1) on both sides and moving the gold cost to the left side of the equation.:

Cost(armour1)+ Cost(armour2)  - 3,000 - 3,000 + 25,000 < Price(slot2)

So using fusion will only be advantageous if:

Price(slot2) > Cost(armour1)+ Cost(armour2)  + 19,000

So if you have to fuse an 18,000 gold armour with a 9,000 gold armour that will only be smart to do if the price  of an extra upgrade slot exceeds 46,000 gold. That will never happen.
