It would be very unwise to make such a substitution. The rubber cone may not be what makes the XC90 bolt superior to the original V70 bolt. The Volvo bolt is a designed torque and stretch bolt. If you would put some high strength rigid bolt in the axle, you might permanently damage the axle and might jam the hub on so it could not be detached.

Supposedly, the new V70 bolt has thread-lock in a different location on the bolt. The only prudent action would be to get the new V70 bolts and fasten them according to the instructions. I believe those instructions are to tighten to a certain torque an then twist through and additional specified angle (90 deg?).
