Replace whole lines in the file from different files

Hi all,
I have two parameter blocks in a configuration file, file1.conf.
First parameter block starts with PWAT-PARM1 and
ends with END PWAT-PARM1.

Second parameter block starts with PWAT-PARM2 and
ends with END PWAT-PARM2 (please see below in file1.conf).
file1.conf is fixed width columns and numeric values are written in fortran format.

I don't know how to update numeric values in file1.conf from two different files, file2.txt and file3.txt for each iteration.
Thus, numeric values in the first parameter block (PWAT-PARM1) should be updated from file2.txt
and, numeric values in the second parameter block (PWAT-PARM2) should be updated from file3.txt

<file1.conf>

Code:

  PWAT-PARM1
*** < PLS>    PETMAX    PETMIN    INFEXP    INFILD    DEEPFR    BASETP    AGWETP
*** x  - x   (deg F)   (deg F)
  101  606       40.       35.        2.        2.       0.1      0.02        0.
  END PWAT-PARM1

  PWAT-PARM2
*** <PLS >     CEPSC      UZSN      NSUR     INTFW       IRC     LZETP
*** x -  x      (in)      (in)                       (1/day)
  101  606       0.1     1.128       0.2      0.75       0.5       0.1
  END PWAT-PARM2

<file2.txt>

Code:

  101  606       20.       15.        1.        1.       0.1      0.12        0.  
  101  606      1.2.       25.        3.      0.5.       0.5      0.22        0.

<file3.txt>

Code:

  101  606       0.2     1.376       0.1      0.25       0.1       1.1 
  101  606        1.     12.76       3.1       1.0       1.1       2.1

After first iteration, for example, file1.conf should look like this.

Code:

  PWAT-PARM1
*** < PLS>    PETMAX    PETMIN    INFEXP    INFILD    DEEPFR    BASETP    AGWETP
*** x  - x   (deg F)   (deg F)
  101  606       20.       15.        1.        1.       0.1      0.12        0. 
  END PWAT-PARM1

  PWAT-PARM2
*** <PLS >     CEPSC      UZSN      NSUR     INTFW       IRC     LZETP
*** x -  x      (in)      (in)                       (1/day)
  101  606       0.2     1.376       0.1      0.25       0.1       1.1 
  END PWAT-PARM2

Seems to me, sed or awk would be a solution, but I don't know how to solve it.
I searched this forum using key word "replace lines" and "replace pattern match", but no luck.
Any help would be greatly appreciated.

Thanks,

Jae
