Anyone atempted crossing Dabai, C. odontophyllium X C. vitiense and more

[cassowary]

*Anyone atempted crossing Dabai, C. odontophyllum X (C. vitiense,C. schweinfurthii or other Canarium sp. like galip, pili etc)?
*Could there be a way to coss Safou d. edulis with c. odontophyllum or through some intermediarie species?
*What about litsea graciae X p. americana or other persea sp.. Or use other Litsea sp. in between. Would be great with a bigger Enkalak.
*Garcinia warenii X g. mangostana, maybe a more cold tollerant mangosteen could come out if it.
*Ficus carica X native AU fig like cluster fig, atherton fig, small fruited fig, sandpaper fig etc. Wouldn't hurt to have a f. carica sweetish fig on a native fig tree

Maybe this is to far out for others but maybe someone already have experience thay could share, that would be great!
