That's a fair statement regarding the possibility of what could happen if Issei obtained Euclid's "artifical" Boosted Gear. However, I would like to put my opinions regarding this question/subject on the table. If one were to compare the two Boosted Gears side-by-side based on current information, the comparison would be considerably similiar to the GN Drives from the series: Gundam 00. How you might ask?

Well, in both cases the "original" and "artificial" can match the majority of their primary functions and in some cases, appearances. In the case of this story, both Boosted Gears have the ability to double the user's power once every ten seconds with the only limit being the user's physical capabilities. That much hasen't changed regarding the Boosted Gears. What is different is how they activate their secondary functions. That is to say both Gears have clearly different methods of activating their Balance Breakers.

According to the spoilers for Volume 16, both Issei's and Euclid's Boosted Gear are capable of the exact same Balance Breaker, Boosted Gear Scale Mail. That, and the functions of both armors are identical based on current information. The biggest difference between them lies in how they're triggered. For Issei, he draws on Ddraig's power to manifest the armor while using his own energy to mantain it. In Euclid's case, his Boosted Gear lacks a dragon sealed inside, never mind lacking one as powerful as Ddraig or Albion. To compenstate for this, Euclid has to sacrifice enough dragons to meet the needs of activating the Scale Mail. What is currently unknown about this method is: is it a part of the Artificial Boosted Gear, or a specific spell designed to absorb energy and/or lifeforce?

If the first holds true and Issei obtains the Artificial Boosted Gear, then he can use that ability. It's been inferred and even demonstrated that take in and utilize powers and abilities as well as converting or amplifying existing ones. In Issei's case, if the Artificial Boosted Gear has a function that allows the user to take in either the unique energy or the lifeforce of another being, including dragons, then at the very least he could have a safer alternative to diversifying his and Ddraig's power. I say this in light of when Issei and Vail fought for the first time in Volume 4 of the light novels. During that fight, Issei make a gamble and took in one of Albion's jewels with the intention of using his own power against him. To anyone who has read the book or seen the show, you know he succeeded but at the cost of his lifespan due to the method used and the nature of the power(s). If the Artificial Boosted Gear works as I hypothsize and Issei obtains it, he could diversify his power with little to fear, especially with all the dragons he has formed connections with. Imagine the possibilities if Issei took in and replicated the powers and/or abilities of Tannin, Fafnir, Yu-long, even Virtra.
