Calf implants. Is it safe to go bigger?

a couple of years ago i had calf implants and i love the results. they are very natural and i have had no problems. i got two implants lateral and medial on each leg. based on my aesthetic goals years later i have come to realise that i actually want my medial part of my calf muscle larger than the lateral. to almost make the leg as a whole to look straighter and have more if a inward direction. is it safe to go one larger in the medial area with a implant? or it is it too risky
