Approach grafting multiple different rootstocks on marcotted pomelo tree

[ILoveCitrus]

I'm planning to add a Calamandarin rootstock and Sour orange rootstock on a marcotted pomelo tree thru approach grafting. Reason is the tree keeps getting knock down by strong winds. Is it advisable to use two different citrus rootstock or it should be only one kind? Thank you.

Sour orange will probably show more compatibility with pomelo than calamandarin.

Does this mean that if i graft a sour orange rootstock on one side and calamandarin on the other side. The calamandarin rootstock would die? Leaving only the marcot pomelo root and sour orange? Thank you for the quick response.
