What's this leading to O Gina?
A classic brand extension situation is selling new product type under an established brand. Had orange juice been previously sold under GINA say GINA ORANGE, then rather straight forward to use GINA LEMON. In the case of ORANGINA, it would not be possible to use ORANGINA for lemonade. ORANGINA is inherently restricted to orange related product. LEMONGINA is not ideal because the public will start to be conditioned that all -GINA suffice names are related to ORANGINA. Less scrupulous might then come in to sell BANANAGINA.
