Yes, by using operator=

#include <stdio.h>

class X {
 int j;

public:
 X(int i) : j(i) { printf("Called X(int=%d): j=%d\n", i, j); }
 X(char *cp, int i) {
    *this = X(i);
    printf("Called X(char *cp= '%s', int=%d): j=%d\n", cp, i, j);
 }
};

main() {
 X x("test", 5);
}

$ main
Called X(int=5): j=5
Called X(char *cp= 'test', int=5): j=5
