When i went over the HSMC specs document I understood it was more general and not board specific.

The HSMC specification was something created by Altera, and only Altera use it. It is *board specific* in that boards that follow the specification should be compatible.

But if its true the HSMC LVDS TX differential lanes can be redefined so that i can use all 34 differential pairs as RX, then that will be perfect.

They cannot be re-defined if you want to call your board HSMC compliant. The specification *states* their direction. You could create a board that does not adhere to the specification, but then you would not call it an HSMC board :)
Bottom line is that you can use the Samtec HSMC connector however you see fit,
but if you want to interface to other HSMC boards, then you must stick to the specification.
