from collections import Counter

def can_construct_palindrome(s, k):
    # Count the frequency of each character in the string
    char_count = Counter(s)
    
    # Count the number of characters with odd frequency
    odd_count = sum(count % 2 for count in char_count.values())
    
    # If k is greater than or equal to the number of odd-count characters,
    # it's possible to construct k palindromic strings
    return k >= odd_count and k <= len(s)
