Infinite-volume composition conjecture for tg-hyperbolic virtual knots and links

Let K1K_1 and K2K_2 be tg-hyperbolic virtual knots or links with genera g1,g2>0g_1,g_2>0. For corks C1iC_1^i and C2C_2, form compositions

Wi=(S1×I,K1,C1i)#ns(S2×I,K2,C2).W_i=(S_1\times I,K_1,C_1^i)\mathbin{\#_{ns}}(S_2\times I,K_2,C_2).

Infinite-volume composition conjecture. There exists a sequence of compositions WiW_i such that

limivol(Wi)=.\lim_{i\to\infty}\operatorname{vol}(W_i)=\infty.

The surrounding discussion presents this as an expected extension of the alternating case and notes that, if true, it would give infinitely many compositions with volumes approaching infinity for any two tg-hyperbolic virtual knots.
