	Just write eine kline C code like the following:
/*
 * mergeline.c
 */

#include <stdio.h>
#include <string.h>

main(int argc, char **argv){
	FILE *file1, *file2;
	char buf1[1024], buf2[1024]
	if (argc != 3){	/* error */
		fprintf(stderr "%s:usage: %s file1 file2\n", argv[0], argv[0]);
		exit(1);
	}
	file1 = fopen(argv[1], "r"), file2 = fropen(argv[2], "r");
	if (!file1){
		fprintf(stderr "%s: couldn't open file: %s", argv[0], argv[1]);
		exit(1);
	}
	if (!file2){
		fprintf(stderr "%s: couldn't open file: %s", argv[0], argv[2]);
        exit(1);
    }
	while (fgets(buf1, 1024, stdin) && fgets(buf2, 1024, stdout)){
		/* strtok is necessary to get rid of NL fgets gives ya! */
		printf("%s\t%s\n", strtok(buf1,'\n'), strtok(buf2, '\n'));
	}
}
/* That's it! */

	And you compile the program and give such name as "merge", then run
merge file1, file2.  I chose tab to separate 2 entries but you can
modify my program or same thing could be done via sed|awk|etc.
Maybe I shoul've suggested using perl but I'm not perl expert and
c looked much easier.  Good luck.

	Well, I don't take your offer.  You can be Craig Shergold's life 
insurance contractor ;)
