How to change plane in campaign?

[TheStarOfAfrica]

Dear forum Members. I want ask is there any possibility, or even program (I have my own original version of IL FB, an Pacific Fighters) to change plane in campaigns in Pacific Fighters to different plane. I'm think about campaign not created by myself, but this original. I want change for myself only from US-campaign-New-Giunei from P39 fighter to P40B/C fighter, and similar from NZRAF, RAAF, and RAF-campaign-Singapore similar from Buffalo MkI fighter to Tomahawk MkII fighter. Can You help me?

That's my dream and I'm not a cracker, or somebody like a haker and I want please You to help me, It's only for my own Use. I Very like P40 B/C fighter, and that's Why I'm talking.

Please Help Me

Best Regards,

Ralph
