No, It is not possible.
Matrix can only hold 256kb Bioses and the X25035 minimum size is 512Kb.
The next "best" (At least for me) Bios for the matrix is the X24981/X24983, but I preffer the 4981 because you can customize some of his options thru Xbox tool.
Now, I am assuming you have a 1.0 or 1.1 Xbox since you have a Matrix, So you can flash your TSOP with the X25035, add a switch and have the best of both worlds (A better Bios than the matrix can hold without loosing the ability to go to live).
I just did that on my 1.1 Xbox and it works great.
