Connecting 2 male headers on a pcb together

I have 2 male headers like this on 2 different boards:

I need to connect 2 such male headers together. One way to do this would be to use something like individual female to female jumper wires. However, I am operating at a frequency of about 32-48 Mhz and don't want such long traces. I wanted something like a female connector on both sides, but I looked through all the types shown here and I still can't find any. Could someone give me any ideas as to what kind of connector I need to use? I dont want to make a PCB just for this.

I would use two female headers like this...

2X20 40Pin Double Row Female Straight Header enter image description here

soldered back to back to make a female-female joiner. If you overlap the contacts they only add 15mm to the overall length (compared to a normal male/female header combination) which should not be significant at 32-48MHz.

If any of your signals still have excessive ringing or ground bounce then you could try inserting small value resistors (10~50Ω) in series between the connectors.
