Change the length of input lines in interdigital filter

Hello,
I have designed an interdigital bandpass filter with microwave office. The problem is that this filter must be used in a board with specific dimensions so I have to draw lines at least from one of input-output connectors to the input-output lines of the filter. Is this going to affect the functionality and-or the performance of the filter2 I am using two identical interdigital filters in this board one for the transmitter and one for the receiver (attached picture). Any ideas on how I can make this work? The board dimensions and connectors can not be changed.

Assuming a reasonable match appart from the insertion loss of PCB material and any cross coupling between the lines their length should have no effect on the filter.

Thanks, this saves me from a lot of trouble!

Would be no performance change only if the lines coming from the filter are 50 ohms (the same impedance as the lines coming from the SMA connectors).
Might be wrong, but I see from the picture that the lines coming from the filters are a little bit narrow, which make their impedance higher than 50 ohms.
